I always wait a week to see what the reaction is to any upgrade (on MacFixit, Macintouch etc.). The end result of that is that I often don't install point upgrades and end up having to use the combo undater anyway (I skipped X.2.2, X.2.4 and X.2.5 b/c of this strategy).
The early reports sound like X.2.6 is a winner.
